Description

CONTAINER WITH FOLDABLE HANDLES

Field of the Invention The present invention pertains generally to the field of packaging and containers, and particularly to food containers having handles attached thereto.

Backqround of the Invention In the area of food packaging; a considerable market has developed for containers in which food may be heated for direct consumption. Suc~1 containers therefore represent a sort of disposable cookware/dishware combination. Today's food containers mu~t be attractive in appearance, easy to use, not messy, pleasant to eat out of and, increasingly importantly, microwavable.
As in conventional dishware, it is advantageous for a food container to include some sort of handle for the user to grip or hold while eating the cooked contents of the container, or otherwise handling the container. However, when such handles are attached to, and protrude from, an outside wall of the container, a significant loss of usable packing space results when the containers are packed for transportation to grocery stores, vending areas, etc. Shelf space would be ~imilarly lost at the point of sale. In some containers, packing space ~hat would be dedicated to the containers and their contents is taken up by handles.
Handles attached to the outside of the container may also detract from an otherwise streamlined and attractive packaging appearance. Inasmuch as the container is bought for its contents, however, the consumer should not be led to believe that a large proportion of the purchase price is reflected in the container or the han~les.
Accordingly, a need has developed for a handle arrangement that allows for an attractive container appearance but is econo~ical to manufacture. The handles should preferably take up a minimum of packing space and ~1 be easy to hold to prevent me~ses and Bpi llage.

SummarY of the Invention In accordance with the present invention, a container with foldable handles includes a plastic container body having a top peripheral edge portion defining the top opening of the container body and a metal closure sealed, secured, seamed, or joined to the container body at its top peripheral edge portion. The closure has means, such as a parting line, score line, or line of weakness which defines an inner panel that can be removed from the remainder of the closure. The closure is preferably a full panel easy opening closure 30ined to the container body, preferably by a double seam to provide a proven, high integrity her~etic seal.

The container also may include a seam protective ring, referred to herein as a seam ring, that is integrally formed with a handle assembly and mounted over the seam between the closure and the container body, among other reasons, to cover and conceal the seam and/or all or substantially all of the metal remaining on the container after the panel is removed. The seam ring has a top portion and inner and outer skirts de~cending dowardly from the top portion. To secure the seam ring in place over the seam, the outer skirt preferably has an inwardly facing bead formed on its inner surface preferably near its bottom peripheral edge. The inwardly facing bead is shaped to fit under the outwardly extending juncture, such aQ the seam of a crimp ~eam or of a double seam, to hold the seam ring in position on the container body. The inner skirt of the seam ring has an inner bottom edge which is spaced cloQely adjacent to the top surface of the closure at a position adjacent to the parting line of the closure such that the area of the central panel of the closure bounded by the parting or score line can be removed, if rigid, without undue interference by the inner s~irt of the seam ring. In this manner the consumer is protected from the raw edge of the rim which remains attached to the container body. This is especially important for soups and the like where the consumer may want to drink directly from the container.
For containers having a ~eam ring, a handle assembly is attached to the inner skirt of the seam ring at a base. For containers which do not utilize a seam ring, the handle assembly may be attached directly to the body of the container near the top opening. In a storage position, the handle assembly is positioned within the inner skirt of the seam ring. The handle assembly includes a central member attached to the base, and two handles attached to opposiny sides of the central member.
Hinges are located between the base and the handle to allow the handle asse~bly to be pivoted from a position within the inner s~irt of the seam ring to a position over the top portion and against the outer skirt of the seam ring. The handle assembly is pivoted to this latter position when in use by a consumer. There are additional hinges that attach each handle to the central member to allow the handles to fold out from a position in which both handles and the central member are planar to a position in which the handles are folded against each other about the central member. When the handles are thus folded, they may be conveniently gripped by a person eating or drinking out of the container.
Because of the foldable nature of the handles, the container of the present invention requires no additional shelf or storage space. The handles are economically manufactured and do not detract from the appearance of the packaging.
Further objects, features, and advantages of the invention will be apparent fro~ the following detailed ;l description when taken in conjunction with the accompanying drawin~s.

Description of the Preferred Embodiment With reference to the drawings, a preferred embodiment of the container of the invention is shown generally at 20 in Fig. 1. The container 20 is comprised of a container body generally designated 22, preferably formed of plastic, which may have a bowl-like shape, as illustrated in Fig. 1, which is preferred where the product is to be used for heating in a ~icrowave oven. This bowl-like shape includes a conventional or other bottom wall and an upwardly curved side wall as shown. Of course, the container body 22 may be sinqle- or multi-layered and have any desired container configuration, including ., ;~.
~, . .

cylindrical, squared, oblong, rectangular, or polygonal.
The container body 22 may be formed of ~ulti-layer plastic as described in United States Patent Nos. 4,497,897 and 4,526,821. A cover or closure 24, preferably formed of metal, is secured at a seal or seam to the top peripheral edge portion 26 of the container body 22 in a manner Xnown to the art. As used herein, any juncture of two or more parts obtained by whatever means may be considered a seam. The closure 24 is preferably a full panel easy open closure having a pull tab 28 attached to it by which a user can pull up and tear off an inner or central panel 30 of the cover 24 which is circumscribed by means such as a line of weakness or score line defining a parting line 32 formed in the closure 24. As is conventional in this packaging technology, the closure 24 is preferably an integral unit which is impervious to both air and moisture until the user breaks the seal at the parting line 32 and removes the inner panel 30 of the cover 24, In accordance with the present in~ention, the ;1 container 20 is also preferably provided with a seam protective ring 34, referred to hereafter as a seam ring, mounted on-thë-top periphery of the container and covering the juncture between the metal closure 24 and the plastic container body 22. The word "ring" as used herein is not limited in terms of size or shape, and may, for example, include a rectangular periphery or other polygonal periphery as well as circular. The seam ring 34 shown has a top portion here preferably illustrated as a ring shaped top portion generally designated 36, an outer skirt 38, and an inner skirt generally designated 40 descended therefrom. The seam ring 34 has a handle assembly 41 attached to the inner skirt 40 of the seam ring. The seam ring has an uppermost inwardly facing surface 42 and includes a horizontal, inwardly extending support ledge 44. The inner skirt 40 descends downwardly from the top portion 36. The inner surface of the seam ring 34 at the ~ -7-inner skirt 40 is composed of an upper section 48 and a lower marginal edqe portion 50. The support ledge 44 is sized and shaped to support the outer peripheral edge portion of an appropriately shaped splash panel 52 (shown in Fig. 3) which may be formed of cardboard, paperboard, plastic, composites, or other suitable material and which may have a hinged tab 54 by which the splash panel 52 may be grasped and manipulated by the user. Tlle tab 54 may be cut from the splash panel 52 as shown to leave a vent opening 56 in the splash panel 52. Preferably, this may be done by maXing a semi-circular cut to define the tab 54, and a second defining a loop starting and terminating on the first cut to define a small hole between the first and second cuts which forms the vent hole 56. The seam ring 34 preferably ha~ means for removably holding the splash panel 52 to the seam ring 34, here shown as preferably including the support ledge 44 and a plurality of engagement lugs 58 which project inwardly from the inward facing surface portion 42 and which are spaced 'I
slightly above the top surface of the support ledqe 44.
The engagement lugs 58 are formed to project over a top surface-'edge~'~portio-n~-of'~'~the''splash panel 52 which are resting on the support ledge 44 and provide a means from restraining upward movement of the splash panel 52.
Preferably, the spacing between the lugs 58 and the surface of the ledge 44 is slightly greater than the thickness of the splash panel 52 so that sufficient space is allowed for the edge portions of the splash panel 52 to bend over the lugs 58 during insertion of the panel 52 and then snap in under the lugs 58 even though the edge portions of the panel 52 may be bent at a sl iqht angle.
The resulting spacing of the underside of the lugs 58 from the top surface of the splash panel 52 as illustrated in Fig. 3, results in positive engage~ents of the lugs 58 to the splash panel 52 w~en the splash panel 52 is movea upwardly from the ledge 44. The luqs 58 can be of any 5" ': . ' `1;' nu~ber. Preferably, they have a downwardly and inwardly angled top surface to facilitate positioning of the splash panel 52 into engagement, and a substantially horizontal undersurface. It is within the scope of the present invention to have other sizes and shapes of lugs so long as they achieve the desired purpose of restraining upward movement of the splash panel 52.
As best shown in cross-sectional views of Figs 2 and 3, the closure 24 is joined, sealed, secured, or seamed to the top peripheral edge portion 26 of the plastic container body 22 by any ~uitable seam, preferably, as shown, by a double seam 60 which extends outwardly from the adjacent outer surface 62 of the container 20. For purpo3e~ of the invention disclo~ed herein, a seal or seam i~ defined as any juncture or joining together of two or more things, obtained by any suitable means. The outer surface of the double seam i9 formed by metal of the closure 24 and thus, when exposed to view, contrasts with the adjacent plastic material of the container body 22. ;1 The metal of the double seam extend~ over the top peripheral edge portion 26 of the container body 22. The top portion 26 ~hd-t-h F spaced apart descending outer skirt 38 and inner skirt 40 of the seam ring 34, which define a channel between them, completely enclose and conceal the double seam and a countersink wall 64 of the closure, which descends from the top of the double seam, and the lip, rim, and the rest of the closure 24 which extends to and is outward of the parting line 32 in the horizontal portion of the closure. The bottom edge, here shown as its inner peripheral edge 66 of the inner skirt 40, terminates at a point touching or spaced above, preferably iust above or close to, the top surface of the panel 30 and preferably just outwardly of the line 32 which circumscribes the removable panel in the closure 24.
~fter the panel 30 is removed, a~ illustrated in the top view of ~'ig. 4, the lip portion 64 of the metal closure 20310~7 that remains will have an inner cut edge G8 at the parting line 32 which may be sharp and could potentially pose the risk of cutting or scraping a user's finger or lip when using the container 20. To minimize the likelihood of this occurring, the inner peripheral edge 66 preferably is in a position which protects the user from being injured on the cut edge 68. Also, preferably, the container body has 8 horizontal shelf 70 preferably provided in the container body 22 just beneath the cut edge 68 that remains on the container body 22. The shelf 70 has an inner edge 72 which preferably lies just beneath or slightly inwardly of the parting line 32. In addition, it is preferred that the inner edge 66 of the sean ring 34 terminate at a po~ition just adjacent to the parting line 32 so that no substantial amount of the remaining metal of the closure 24 extends inwardly from the edge 66 which could cause injury to a user's finger, hand, or lip.
Preferably, the inner edge 66 of the inner skirt 40 on the sea~ ring 34 is spaced relative to, preferably slightly ;~
outwardly fro~ the parting line so that the seam ring 34 does not unduly interfere with the removal of the inner panel 30 from the~cLo~ure 64, but is nonetheless sufficiently close to the parting line 32 that no qubstantial amount of metal remains exposed. A preferred outward spacing of the inner edge 66 from the parting line 32 is a distance which is such that the user's finger cannot exert sufficient pressure on the remaining exposed metal edge itself, because of the support provided by the adjacent plastic, to cut or scrape the skin. Preferably, this spacing may be less than twenty thousandths of an inch.
The handle asse~bly 41 is attached to the inner skirt 40 of the seam ring 34 at a base 76. It should be understood that the handle assembly may also be directly attached to the container body at a position near the top opening of the containers. As shown in Fig. l, prior to .

use by the consumer, the handle assembly 41 is packaged so as to be positioned within the inner skirt 40 of the seam ring 34 between the closure 24 and the splashguard 52.
The handle assembly is so designed that it supports the splash guard. When filled containers are stacked one above the other, this support keeps the splash guard from deflecting downwards out of the lugs 58. The handle assembly 41 includes a central member 78 that is attached to the base 76, the central memher 78 extending inwardly and radially from the point at which the base 76 is attached to the inner skirt 40 of the seam ring 34. The handle assembly 41 comprises two handles 80 attached to opposing sides of the central member 78: each handle 80 includes a first strut 82 and a second strut 84 that extend perpendicular to the central member 78 and are attached to the central member 78 at hinges 86 and 88, respectively. The hinges 86 and 88 are "living hinges."
A third strut 90 is oriented axially to the central member 78 and is joined to the first and ~econd strutC 82 and 84. The first and third strut~ 82 and 90 are joined to form a rounded edge so-a~--to--give--the appearance of one continuous strut. The end 92 of the third strut 90 opposing the end joined to the first strut 82 is flared slightly.
There are two additional hinges 94 and 96 located between the base 76 and the central member 78. The hinges 94 and 96 are "living hinges." The hinge 94 allows the handle assembly 41 to be pivoted from within the inner skirt 40 of the seam ring 34 such as depicted in Fig. 4.
~he hinge 96 allows the handle assembly 41 to be pivoted over the top portion 26 and against the outer skirt 38 of the seam ring 34. In the latter position, the central member 78 abuts against the outer skirt 38 of the seam ring 34 and is depicted in Fig. 6. Fig. 6 further shows the two handles 80 being folded about the central member 78 at the hinges 86 and 88. Thus, upon removal of the splash panel 52, a consumer m~y pivot the handle assembly 41 at hinges 86 and 88 and fold the handles 80 at hinges 94 and 96 so that the handle assembly 41 forms a mean~ hy which the consu~er may grip the container 10 while eatinq or drinkinq tl~erefrom or otherwise handling the container 20. Fiq. 6 shows a manner in which the handles 80 woul~
be typically held or gripped by a user. The grip of the consumer is typically formed around the handles 80 such that the index finqer is inserte~ through the spaces formed between the first, second, and third struts 82, 8~, and 90. The flared end 92 of the first strut 82 keeps the middle finger from slipping off of the handles 80. In Fig. 7, the lateral strut attached to 78 fits under the shoulder of the container. Thi8 helps to prevent the container from twisting away from the handles when the assembly of Fig. 6 is lifted and tilted towards the mouth. Detailed and section views of the handle asqembly 41 are shown in Figs. 7, 8, and 9.
Means are provided on the seam ring 34 for securing the seam ring 34 to the container body 22. For example, an inwardly facinq bead 102 is preferably provided on the inner surface of the outer skirt ~8 and is shaped to fit under the outwardly extending bead of the double seam 60 on the container body 22, preferably to enqage aqainst it, to hold the seam ring 34 in position so that the seam ring 34 cannot be pulled upwardly once it has snapped into place. The inwardly facing bead 102 preferably has the anqle~ surfaces as s~own to best accommodate the snap fitting of the seam ring 34 ovcr the double seam bead.
The plastic materials of which the seàm ring ~ay he formed are sufficiently resilient to be positione~ over the seam such that the inner and outer skirts 40 and 38 can spread away from one another to allow the skirts to snap over the bead of the douhle seam 60, but will nontheless firmly hold the douhle seam 60 between them when they are fitted into p]ace. The angled inner walls ,~, .. . .
. .

` 2031067 of the bead 102 on the outer skirt 38 are preferred also for ease of production of the seam ring 34 in in~ection molding equipment, and particularly to facilitate the removal of the mol~e~ part from the mold without requiring un~ue distortion of the molded seam ring during the removal process.
Preferably, an opening 108 in the support ledge 44 is formed directly beneath each of the lugs 58. The openings 108 are a consequence of the preferred manner of forming the lugs 5~ as the seam rin~ 34 i3 molded in iniection molding apparatus, wherein exten~ed protrusions fro~ one portion of the mol~ extend up to form the ~ottom surface of each of the lugs 58. The support ledge 44 is then formed as mol~ing plastic flows about these protrusions.
When the mold parts are withdrawn from one another and the protrusions are with~rawn from the lugs 58, the openings 10~ are left in the bottom surface of the support ledge 44. As a consequence of this molding proces.s, an indentation is formed in the inwardly facing surface 42 ,l between the ledge 44 an~ each of the lugs 58. In thi.s manner, the en~agement lugs S~ may be forme~ by injection mol~ing in a ~traightforward and efficient~manner even ~
though they form a sharply defined surface ~arallel to and preferably overhanging the support ledqe 44 below. This sharply defined bottom surface of the lug 58 allows the edge of the splAsh panel 52 to be Xept in position, hel~, or firmly engage~3 between the bottom surface of each lug 58 an-3 the top surface of the support le~ge 44. It is to he understood that although the opening 108 has been shown as com~letely encircled ~y the plastic of the seam ring, the opening 108 can continue through the inner skirt 40, forming a slot in the inner skirt 40 beneath the position of each lu~ 58 and serves the same function of facilitating the in~ection mol~ing of the seam ring 34 with the lugs 5~.

20310~7 -~3-~ s ~est shown in Fig. 3, the sp]ash panel 52 is supported on the sup~ort led~e 44 preferably a substantial distance above the inner panel 30 of the metal closure 2~. The container 20 usually has a headspace but may, of course, be filled up to or near to the to~ edge 72 of tlle main portion of the container body 22. Thus, when the panel 30 of the cover 24 is removed, and the splash panel 52 is inserted and placed by the consumer when the product is to be heated in a microwave oven, the splash panel 52 will be supported by a significant distance, Dreferably 3/16 to a quarter of an inch or more, above the top level of the product, e.g., food stuff within the container 20.
The space between the splash panel 52 ana the product allows steam escaping from the side~ to have a clear path to the center vent openinn 56 in the splash panel 52. It is also allows for food expansion 80 that the venting path is not blocked and so that food itself is not expelled through the vent hole 58 onto the panel. ~' The closure 24 may be formed of any suitable ~etal ;
such as those currently u~ed in packaging including plated or coated steel, or aluminum, as desired, and foil plastic laminates. Aluminum generally-w~ l-be-heated-less by--induction in a microwave oven than steel, and thus may be preferred for microwavable containers where a residual metal rim is left on the opened container.
The material of the container body 22 may be selected of any suitable plastic or plastic surfaced composite material; for example, those currently used to form such containers, depen~ing in part upon the process selecte~
for forming the container body. The seam rinq 34 and the handle assembly 41 is prefer~hly integral~y formed ~y injection molding and any of the YariOUS materials suitable for injection molding, successful utilization of the seam ring, and other preferred methods of manufacture may be utilized. For aesthetic compatibility hetween the seam ring 34 ~nd the container body 22, it is preferred 1 ; ~

that the seam ring 4 material match in color and texture of the material of the conta;ner body 22, although it i 5 also possible, and sometimes constitutes a distinct advantage of the present invention, to llave a seam rinq of a different color than the container body to match trade dress colors of the packer or contribute to the visual impact of the completed product. Polypropylene is the preferred material because of its ability to withstand the repeated flexinq of a "living hinge." However, because this is essentially a single use application, other materials with less flex resistance may be used. In particular, blends or co-polymers of polyolefins containin~ a polypropylene component are preferred because the plastic material should also have a heat distortion temperature higher than the temperature which t~e ~eam ring 34 will be heated to during microwaving. Preferably, the material has a heat deflection under flexural load (as defined in ASTM D648) above the boiling point of water.
Those skilled in t~e art will be able to select ~uitable 'I
materials for forming the seam rings of this invention.
It is under~tood that the invention i~ not confined to the particular construction and arranqement of~parts~ ~~~~ ~~ ~
herein illustrated and described. For exa~ple, alternate embodiments may include a foldable handle or outer ~urface of a container neck, and handle per se, adapted to be utilized with various plastic containers having seamed-on ~includin~ crimped on) ends. The invention therefore embraces such mo~ified forms thereof as come within the scope of the following claims.
